Spell Skull

Duration: Concentration, up to 1 minute This spell animates a skull and allows you to implant a spell into it. After you cast this spell, the skull levitates and remains in your space until you command otherwise. You can cast another spell of 3rd level or lower into the skull (although you can cast this spell using a higher-level slot for increased effect). This second spell does not take effect until you wish it. As a bonus action, you can mentally order the skull to fly at a speed of 30 feet, but the skull must remain within 120 feet of you. You can mentally command the implanted spell to trigger as a bonus action, with the skull serving as that spell’s point of origin, at which point the spell skull ends. The implanted spell cannot be one that targets individual creatures, such as acid arrow or chill touch, and it must have a duration of instantaneous. If you end this spell or cease concentrating on it, any implanted spell is lost without effect.
